IMPROVED STEAM-DEVICE FOR WASHING BUILDINGS.

The Schedule referred to in these Letters Patentand making part of 'thesame.

To all whom it may concern:

Be it known that 1, CHARLES NIVERT, of Paris,,

France, haveinvented anImproved Apparatus for Washing Buildings, &c.;and I do hereby declare the following to be a full, clear, andexactdescription of the same. A

My inventim'i relates to an apparatus for throwing water or otherliquids upon structures or other places to be cleansed, and consists ofdevices, fully described hereafter, for accomplishing the said purpose.

In order to enable others skilled in the art to makeand use myinvention, '1 will now proceed to describe its construction andoperation, reference being bad to the accompanying drawing, which formsa part of this specification, and in which- Figure 1 is a sectionalelevation of my-improved cleaning-appalatus Figure 2, a. plan View;

Figure 3,-a detached View of part of the apparatus; and a Figure 4, aviewillustrating the manner of using the apparatus for cleaning thefronts of buildings.

and is discharged from the injectors, on the admission,

or steam into the latter, the water passing into the flexible hose, fromwhiclr it-is discharged with such force as .to thoroughly cleanse thebuilding or other object against which it is thrown.

I In order to reach the more elevated portions of a building, the hosemay extendto a scaffold suspended in front of the building, so as to beadjustable vertically.

I As thewa-ter is heated by its contact with the steam in the injectors,it has a more thorough cleansing eflect than a stream; or streams ofwater discharged by the action of a pump. In some instances, however,where warm water would not be efficient, the desired result maybeproduced by the use of alkaline or other solutions, the latter beingintroduced into the reservoir 0, from which they are discharged in thesame manner as the water.

' It will be apparent that owing to the portability of the apparatus,structures and places which otherwise could not be reached for washingmay be easily and economically cleaned.

I am aware that in locomotives and other apparatus steam-generators andinjectors are arranged together upon a truck; I therefore do not claimbroadly sucha combination. It will be seen that my device, owing to thepeculiar arrangement of the parts thereof, performs a function which isnot attained in the machines referred to.

I claim as my iuventiomand desire to secure by Letters Patent- Thecombination of the iniectorsA A, their delivery-pipes f, tank 0,communicating, through pipes a a, with the injectors, andsteam-generators G, communicating with the, injectors, through pipes 11,the whole being arranged and constructed as herein set forth.

In testimony whereof, I have signed my name to this specification, inthe presepce of two-subscribing witnesses.
